To all whom t may Concern:

Be it known that I, OSCAR B. IiiN'rNnn, a citizen of the United States,residing at Potwin, in the county of Butler and State of Kansas, haveinvented certain new and useful Improvements in Shears; and l do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to shears provided with pivoted cutters andoperated by compound levers; and it consists in the novel constructionand combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of a shears constructedaccording to this in vention. Fig. 2 is a plan AView of the same.

The machine is provided with a supporting` base 2, and 3 and 4 are twouprights secured to the base. These two nprights are similar' to eachother, and each is formed of two side plates having a guide channel 5between them, and the upright 3 has a curved extension 6 at its topwhich forms a guide for the pivoted blade. The pivoted blade 7 ispivoted to the top of the upright 4 and projects through the guidechannel of the upright 3.

A stationary blade 8 is secured horizomV tally between the upper partsof the uprights 3 and l in any approved manner, and is arranged inoperative relation to the pivoted blade.

A lever 10 is pivoted by a pin 11 in the guide channel of the upright 3,and one end of the lever 10 is pivotally connected with the free end ofthe blade 7 by a link 12 and pins 13. The other end portion of the lever10 is provided with a forked jaw 141 which is arranged at an angle toits main portion. A lever 15 is pivoted at one end to a lug 16 on theupright 3, below the stationary blade, by means of a pin 17, and theother end portion of the lever 15 works in the guide channel oi theupright 4L. The middle part ot' the lever 15 has a longitudinal slot 18,and 19 is a pin which slides in the slot 18 and connects the 'forked jawwith the lever 15.

A handle 20 is provided and has a curved lower end portion 21 which ispivoted by a pin Q9. to the end of the lever 15 which projects throughthe upright 4. The handle is pivoted to the upper part of a rockerarm211, which is pivoted to the base by a bracket 25 and a pin 2G, and thisrocker-arm forms a movable 'fnlcrnni -for the handle. The pivoted bladeis shown in its raised position in Fig. 1, and when the handle is movedto the left, it operates the compound levers, and the pivoted bladedescends and ents oil' any object inserted between the blades.

`What I claim is:

In a shears, the combination, with two uprights, and a stationary bladesecured between them; of ablade pivoted to one of the uprights, a leverpivoted to the other npright and having a 'forked jaw at one endarranged at an angle to its main portion and provided 1with a pin, alink pivotally conneeting the Ytree end portion ot' the pivoted bladewith the adjacent end portion of the said lever, a second lever pivotedto the last said upright above the pivot oi the said lever and having alongitudinal slot at its middle part which engages with the said pin, ahandle pivoted to the free end portion of the second lever, and apivoted roeker-arm which supports the said handle and forms a movable'nlcrum Jfor it.

In testimony whereof I have ailixed my signature in the presence of twowitnesses.
